Richard P. Gabriel is an American computer scientist known for his work in computing related to the programming language Lisp, and especially Common Lisp. His best known work was a 1990 essay "Lisp: Good News, Bad News, How to Win Big", which introduced the phrase Worse is Better, and his set of benchmarks for Lisp, termed Gabriel Benchmarks, published in 1985 as Performance and evaluation of Lisp systems. These became a standard way to benchmark Lisp implementations.
After earning a PhD, he continued to work on AI projects for McCarthy, although his thesis advisor was Terry Winograd. He eventually began working for Lawrence Livermore National Laboratory, where he recruited several of the researchers and programmers for a company, Lucid, Incorporated, he founded in 1984 and would leave in 1992. It survived until 1994. Gabriel was at various times the President and Chairman of Lucid Inc. The product the company shipped was a Lisp integrated development environment for Sun Microsystems’ reduced instruction set computerhardware architecture named SPARC. This sidestepped the main failure of Lisp machines by, in essence, rewriting the Lisp machine IDE for use on a more cost-effective and less moribund architecture. During this time, Gabriel married his second wife, and had a daughter; he later divorced his second wife in 1993. Eventually Lucid's focus shifted to an IDE for C++. A core component of the IDE was Richard Stallman’s version of Emacs, GNU Emacs. GNU Emacs was not up to Lucid’s needs, however, and several Lucid programmers were assigned to help develop GNU Emacs. Friction arose between the programmers and Stallman over how to handle graphical user interface issues, and Lucid forked Emacs, and thus became mainly responsible for the birth of what would come to be called XEmacs. One of his hires was another notable programmer, Jamie W. Zawinski.
Own business and open-source software
After Gabriel left Lucid, Inc. for good, he became a Vice President of Development for ParcPlace Systems, and then a consultant, for, among others, Aspen Smallworks, before joining Sun Microsystems as a Distinguished Engineer. There, Gabriel was an influential contributor to the evolution of the open source software strategy, culminating in publication of the book Innovation Happens Elsewhere. In 2007, he joined IBM Research as a Distinguished Engineer.
Association for Computing Machinery
Gabriel has received the Association for Computing Machinery's 1998 Fellows Award, and its 2004 ACM-AAAI Allen Newell Award. The citation reads: “For innovations in programming languages and software design, and promoting the interaction between computer science and other disciplines, notably architecture and poetry.” He was chairman of the Object-Oriented Programming, Systems, Languages & Applications conference in 2007.
Poetry
In 1998 he received his MFA in Poetry from Warren Wilson College. He has published poems in some literary journals. His chapbook, Drive On, was published by Hollyridge Press in 2005.
